POAG: primary open-angle glaucoma; PLT: platelet count; PDW: platelet distribution width; PCT: plateletcrit; MPV: mean platelet volume; P-LCR: platelet large cell ratio; IOP, intraocular pressure; VCDR, vertical cup-disc ratio; MD, visual field mean deviation; MS, visual fields mean sensitivity. One-sample Kolmogorov–Smirnov test . Spearman correlation was used.
